The Nostromo is returning to Earth but where is it returning from? (Thedus; as for that backstory, haven't a clue yet)

How many tons of mineral ore is the Nostromo carrying? (20 million tonnes)

The nostromo: The normal complement is a crew of 7, consisting of the captain, first officer, technical administrator, pilot, science officer, instrumentation technician, and hardware technician. They have no skills with relation to the cargo they are towing, but are only necessary for pickup and delivery of the material..

The Company
The Weyland-Yutani Joint Stock Corporation, commonly refered to as "The Company", is the largest single Megacorporation in the 22nd century. Founded in 2109 by Mr. John Weyland and his business partner Charles Yutani, and financed by a number of individuals and smaller companies, we are devoted to the colonization of other worlds and the betterment of society. Whether through the discovery of new and better medical technics, the colonization and harvesting of the resources of alien worlds, or the advance of amazing new technology, our goal is to serve mankind.
Some of our more incredible creations are the invention of Hypersleep, which has aided our jurney through the stars greatly; motion trackers, which are now an indespensible military asset; and the awesome Atmospheric Proscessor, which we manufacture for colonizing otherwise uninhabitable planets.
So you see how we are truely "Building better worlds".
While we have close ties with other Corporations such as Hyperdyne, a synthetic manufacturor, there are others which we are in direct competition with. Normally they do not pose a great threat though, and any problems that may arise are dealt with swiftly.
